Atomically Thin Amorphous Carbon with an Ultralow Dielectric Constant
Chee-Tat Toh, Artem K. Grebenko, Ugur Karadeniz +17
Two-dimensional (2D) materials exhibit excellent properties at monolayer thickness and are viable replacements for various microelectronic components as scaling gradually approache…
From Ultrafast Demagnetization to Ultrafast Spintronics : a 30 years story
Quentin Remy, Stéphane Mangin
The discovery of femtosecond laser-induced ultrafast demagnetization in 1996 opened a new field, femtomagnetism, in which magnetic order can be quenched on timescales shorter than…
Ultrafast controlling net magnetization in g-wave altermagnets via laser fields
Zhaobo Zhou, Sangeeta Sharma, Junjie He
The diverse nodal spin structures in d/g/i-wave altermagnets (AM) may cause distinct light-induced spin responses yet remain poorly understood. Using time-dependent density functio…
Generation of Phonons with Angular Momentum During Ultrafast Demagnetization
M. S. Mrudul, Markus Weißenhofer, Peter M. Oppeneer
A major question in the field of femtosecond laser-induced demagnetization is whereto the angular momentum lost by the electrons is transferred. Recent ultrafast electron diffracti…
Momentum-Resolved Signatures of Carrier Screening Effects on Electron-Phonon Coupling in MoS
Yiming Pan, Patrick-Nigel Hildebrandt, Daniela Zahn +5
Electron-phonon coupling is central to many condensed matter phenomena. Harnessing these effects for novel material functionality in materials always involves non-equilibrium elect…
BaZrS Lights Up: The Interplay of Electrons, Photons, and Phonons in Strongly Luminescent Single Crystals
Rasmus Svejstrup Nielsen, Ángel Labordet Álvarez, Yvonne Tomm +8
Chalcogenide perovskites have emerged as a promising class of materials for the next generation of optoelectronic applications, with BaZrS attracting significant attenti…
